844001 - Block Diagram
Description
The 844001 is a Fibre Channel clock generator that uses an 18pF parallel resonant crystal over the range of 20.4MHz - 28.3MHz. For Fibre Channel applications, a 26.5625MHz crystal is used. The frequency select pin allows the device to generate either 106.25MHz or 212.5MHz from a 26.5625MHz crystal. To generate 187.5MHz for 12Gb Ethernet, a 23.4375MHz crystal is used. The 844001 uses our 3rd generation low phase noise VCO technology and can achieve <1ps typical rms phase jitter, easily meeting Fibre Channel and Ethernet jitter requirements. The 844001 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
